DTC P0101: Notes
DTC P0101 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0101 |
MAF circuit range/performance problem |
| DETECTION CONDITION |
- PCM monitors mass intake air flow amount when the engine is running.
- If mass intake air flow amount is above 50 l/s
for 5 s
and engine speed is below 2,000 RPM
with engine running, PCM determines that detected mass intake air flow amount is too high.
- If mass intake air flow amount is below 6.0-57.8 l/s
(The value depends on engine speed). for 5 s
and engine speed is above 1,000 RPM with engine running and throttle opening angle is above 50%
, PCM determines that detected mass intake air flow amount is too low.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.
